背景

特殊场景需要变更合约PolygonZkEVM.sol中的TrustedSequencerURL

合约代码

/**
     * @notice Allow the admin to set the trusted sequencer URL
     * @param newTrustedSequencerURL URL of trusted sequencer
     */
    function setTrustedSequencerURL(
        string memory newTrustedSequencerURL
    ) external onlyAdmin {
        trustedSequencerURL = newTrustedSequencerURL;

        emit SetTrustedSequencerURL(newTrustedSequencerURL);
    }

ABI

[{
      "inputs": [
        {
          "internalType": "string",
          "name": "newTrustedSequencerURL",
          "type": "string"
        }
      ],
      "name": "setTrustedSequencerURL",
      "outputs": [],
      "stateMutability": "nonpayable",
      "type": "function"
    }]

测试

当前合约内TrustedSequencerURL：http://172.18.36.173:8123
期望变更为：http://172.18.39.162:8123

PolygonZkEVM合约地址在create_rollup_output.json->rollupAddress: 0x584eF34da0d700082d3c29cD3844d9524e656950

import { ethers } from 'hardhat';
import path from 'path';
import fs from 'fs';
require('dotenv').config({ path: path.resolve(__dirname, '../.env') });
import createRollupParameters from './create_rollup_output.json';

async function main() {
    const privateKey = path.join(__dirname, 'keystore', './admin.privateKey');
    const data = fs.readFileSync(privateKey, 'UTF-8');
    const wa = new ethers.Wallet(data, ethers.provider);
    console.log(`Use ${wa.address}`);
    const polygonZkEVM = (await ethers.getContractFactory('PolygonZkEVM', wa)).attach(createRollupParameters.rollupAddress);
    console.log(await polygonZkEVM.trustedSequencerURL());
    const tx = await polygonZkEVM.setTrustedSequencerURL("http://172.18.39.162:8123");
    await tx.wait(1);
    console.log(await polygonZkEVM.trustedSequencerURL());
}

main().catch((error) => {
    console.error(error);
    process.exit(1);
});
